Provided are a method and apparatus for acquiring multimedia broadcast/multicast service (MBMS) service area information in a wireless communication system. User equipment (UE) acquires at least one first MBMS service area identity (SAI), which corresponds to a MBMS service provided at a first carrier frequency, from system information broadcasted from a first cell. The UE acquires at least one second carrier frequency, which neighbors the first carrier frequency and at which the MBMS service is provided, and at least one second MBMS SAI, which corresponds to the MBMS service provided at the at least one second carrier frequency, from the system information.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A method of communicating between a user equipment (UE) and a network in a mobile communication system, the method comprising: receiving, by the UE, a multimedia broadcast multimedia service (MBMS) service from a first cell in a first frequency while the UE is in an idle mode; receiving, by the UE, a first system information block (SIB) from the first cell in the first frequency, the first SIB including information on an MBMS service area (SA) provided at a second frequency; receiving, by the UE, a second SIB from a second cell in the second frequency, the second SIB including information on a multimedia broadcast multicast single frequency network (MBSFN) area; and receiving, by the UE, the MBMS service from the second cell in the second frequency.
A mobile device in a wireless network, while in an idle state, receives a multimedia broadcast/multicast service (MBMS) from a first cell using a first frequency. The device also receives system information (SIB) from this first cell that includes information about MBMS service areas available on a second frequency. Subsequently, the device receives another system information block (SIB) from a second cell operating on the second frequency, and this SIB contains information about a multimedia broadcast multicast single frequency network (MBSFN) area. Finally, the mobile device receives the MBMS service from the second cell at the second frequency.

The device prioritizes neighboring frequencies for the MBMS service.
4. The method of claim 1 , wherein the MBMS service corresponds to the MBMS SA.
The method of communicating between a user equipment (UE) and a network, where the UE receives MBMS from a first cell in a first frequency while idle; receives a first SIB from the first cell that includes information on an MBMS service area at a second frequency; receives a second SIB from a second cell at the second frequency including MBSFN area information; and receives the MBMS service from the second cell at the second frequency, wherein the MBMS service corresponds to the MBMS service area.

5. The method of claim 1 , wherein the first SIB and the second SIB are received while the UE is in the idle mode.
The method of communicating between a user equipment (UE) and a network, where the UE receives MBMS from a first cell in a first frequency while idle; receives a first SIB from the first cell that includes information on an MBMS service area at a second frequency; receives a second SIB from a second cell at the second frequency including MBSFN area information; and receives the MBMS service from the second cell at the second frequency, wherein the first and second SIBs are received while the UE is in idle mode. The device learns about new MBMS opportunities without requiring active connection.
6. The method of claim 1 , wherein the first SIB is a SIB 15.

The MBMS service area info is broadcast in a specific SIB message type.
7. The method of claim 1 , wherein the second SIB is a SIB 13.
The method of communicating between a user equipment (UE) and a network, where the UE receives MBMS from a first cell in a first frequency while idle; receives a first SIB from the first cell that includes information on an MBMS service area at a second frequency; receives a second SIB from a second cell at the second frequency including MBSFN area information; and receives the MBMS service from the second cell at the second frequency, wherein the second SIB is a SIB 13. The MBSFN area information is broadcast in a specific SIB message type.
8. A user equipment (UE) configured to communicate with a network in a mobile communication system, the UE comprising: a transceiver; and a processor, coupled to the transceiver, that: controls the transceiver to receive a multimedia broadcast multimedia service (MBMS) service from a first cell in the first frequency while the UE is in an idle mode; controls the transceiver to receive a first system information block (SIB) from the first cell in a first frequency, the first SIB including information on an MBMS service area (SA) provided at a second frequency, controls the transceiver to receive a second SIB from a second cell in the second frequency, the second SIB including information on a multimedia broadcast multicast single frequency network (MBSFN) area, and controls the transceiver to receive the MBMS service from the second cell in the second frequency.
